ElGHT-DAY-CLOCK ALARM.

SPECIFICATION forming part of Letters Patent No. 297,612, dated April 29, 1884.

Applicationfiled August 15, 1883. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, G. FRED. LUQUER, of Montgomery, in the county of Orange and State of New York, have invented a new and Improved Eight-Day Alarm Attachment for Clocks, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a front elevation of my improvement, part of the frame being removed, and showing a part of the cloclodial. Fig. 2 is a side elevation of the lower part of the same.

The object of this invention is to provide alarm attachments for clocks constructed in such a manner that they will sound an alarm once each day for eight successive days with one winding up of the spring, so that the alarm mechanism will require to be wound up only once a week.

The invention consists in an eight-day alarm attachment for clocks, constructed with a-dial and cam connected with the clockwork, and operating a lever connected by wires with an arm attached to the pallet, and with a lever arranged to engage with stop-pins attached to the pallet-wheel, and provided with afollower to engage with a trip-wheel connected with the main wheel, driven by a spring, as will be hereinafter fully described.

A represents the dial, and B the hands, of an ordinary eight-day clock. Ois the alarmdial. D is the cam. E is the drop-lever. F is the pallet connecting-wire. G is the palletarm. H is the pallet. I is the pallet-wheel. J is the main wheel. K is the spring. L is the bell-hammer, and M is the bell, all of which parts are constructed and operate in the same manner as in an ordinary alarm, except that the spring K is made longer than is necessary in a one-day alarm.

To the outer part of the side of the palletwheel I are attached two pins, N, at a little distance apart, and at the same distance from the center of the said wheel. 0 is the stop-lever, the forward end of which is widened, so that it will engage with either of the stop-pins N. The stop-lever O is pivoted to the frame P of the alar1n-work, and its rear end is connected with the drop-lever E by the wire Q.

To the rear arm of the stop-lever O is attached a pawl or follower, It, the free end of which rests upon the rim of the trip-wheel S. The trip-wheel S is rigidly connected with the main wheel J, or its post, and has a notch or re-entrant tooth, T, formed in its rim for the follower R to drop into at each revolution of the said wheel S. The forward side of the notch T is square or radial, and its rear side is inclined, so that the follower R will readily pass out of the said notch as the trip-wheel S continues its revolution.

In setting the mechanism, if the alarm is to be sounded within twelve hours, the forward end of the lever 0 must be arranged to rest against the second pin N, which can be done by moving the alarm-dial O, and the various parts will then be in the following positions. The arm G is raised, causing the pallet H to hold the wheel I from revolving, the rear end of the lever O is raised, raising the follower R from the notch T, and disengaging the forward end of the said lever 0 from the second pin N. WVith this arrangement, at the time for which the alarm was set the end of the lever E drops from the shoulder of the cam D, releasing the pallet H and allowing the alarm to be sounded. At the same time the follower R rides along the rim of the wheel S until it reaches and drops into the notch T, drawing the rear arm of the lever O downward, and raising the forward end of the said lever into such a position that the first pin N will strike against it, stopping the alarm-work, and holding it from moving until the cam D has raised the lever E and locked the pallet H, which movement has also lowered the inner end of the lever 0 out of engagement with the first pin N. At the end of the next twelve hours the lever E again drops from the shoulder of the cam D, which releases the pallet H, and at the same time raises the forward end of the lever O into the space between the pins N, so that the said end will be struck by the second pin N and the movement stopped before the alarm has had time to sound, and until the forward movement of the cam D locks the pallet H, as before stated, and releases the second pin N from the lo IOO ver 0, the forward movement of the alarmworks from the action of the spring K, being enough in each case to cause the return of the forward end of the lever O to the rear of the pin N, from the forward side of which it was last released. At the end of the next twelve hours, when the lever E drops from the shoulder of the cam l), the alarm mechanism is released, as before stated, and the alarm is sounded until the wheel J has made an entire revolution, and the forward end of the lever O is again raised to meet the first pin N.

Having thus described my invent-i on, I claim as new and desire to secure by Letters 1atent 1. An eight-day alarm attachment for clocks. constructed substantially as herein shown and described, and consisting of the dial and cam G I), the lever B, the connecting-wire, palletarm, and pallet 11 G H, the connectingwire (Q, and the lever 0, having follower 11, the palletwheel I, having stop-pins N N, the main wheel .I, having trip-wheel S, and the spring K, as set forth.

2. In an alarm attachment for clocks, the combination,with the drop-lever E, the palletwheel I, and the main wheel J, of the connecting-wire Q, the lever 0, having follower It, the two pins X, and the trip-wheel S, having notch 'l, substantially as herein shown and described, whereby the alarm is made to sound successively each day for a week with one winding of the alarm-spring, as set forth.
